Control and Operational Characteristics Research on Multi-Terminal HVDC for Wind Power Transmission

Abstract:

This paper proposed the line-commutated converter based multi-terminal HVDC (LCC-MTDC) combining with the static synchronous compensator (STATCOM) for doubly-fed induction generator (DFIG) based wind farms integration with bulk wind power transmission over long distance. This paper is aimed at the control strategy design and the operational characteristics research of LCC-MTDC for wind power transmission. Then, the control methodologies of the complex integration system are addressed from two aspects: the MTDC and the wind farm. The coordination control strategy is developed to ensure the stable operation of the MTDC system and the wind farm controller is designed to capture the maximum wind power and ensure all the wind power transferred into the MTDC. Simulation results in PSCAD/EMTDC show that LCC-MTDC could achieve desirable operational performances with the control strategy proposed.
